The crash happens here:

      /* The second value is the structure value address unless this is
	 passed as an "invisible" first argument.  */
      if (targetm.calls.struct_value_rtx (TREE_TYPE (cfun->decl), 0))
	size += GET_MODE_SIZE (Pmode);

This code fragment has been changed in DJ's recent targhooks patch:

       /* The second value is the structure value address unless this is
         passed as an "invisible" first argument.  */
-      if (struct_value_rtx)
+      if (targetm.calls.struct_value_rtx (TREE_TYPE (cfun->decl), 0))
        size += GET_MODE_SIZE (Pmode);
